Description

Technical Field

[0001] This utility model relates to the field of oil drum gripping hook technology, and in particular to a small oil drum gripping hook anti-slip structure. Background Technology

[0002] Oil drum grabbers are practical tools specifically designed for moving oil drums. They play a crucial role in industries involving oil drum transfer, such as petroleum, chemical, and warehousing logistics. Oil drum grabbers are easy to operate and can quickly and efficiently move one or more oil drums, significantly improving work efficiency, reducing labor costs, and ensuring the safety and stability of the oil drum handling process.

[0003] Existing technologies, such as the utility model patent with publication number CN209758216U, disclose an oil drum gripping mechanism. This patent uses an upper ring with a handle. At least three chains are evenly distributed circumferentially on the lower side of the upper ring. One end of each chain is connected to the ring, and the other end is arranged at an angle. The lower ends of all chains intersect the horizontal plane at the same horizontal circumference, which is designated as a reference circle. The center of the reference circle and the center of the upper ring share a vertical line, which is designated as the central axis. A gripper is provided on the lower side of the chain. Each gripper includes a C-shaped buckle and a movable inner hook. The opening of the C-shaped buckle faces inward, and the middle of the C-shaped buckle... It is equipped with a long, narrow through groove. The movable inner hook includes a hook shank and a hook claw. The hook shank is long and narrow, and the hook claw is located on one side along the length of the hook shank. The hook claw is bent inward. The side of the hook shank away from the hook claw along its length is pinned to the lower side of the chain. The side of the hook shank near the hook claw passes through the through groove and is located inside the C-shaped fastener. The hook shank is hinged to the C-shaped fastener at the through groove of the C-shaped fastener. This solves the problem that most of the loading or transportation is done manually. Because the oil drum is cylindrical and heavy, it is difficult to move manually. Also, because there are no suspension points on the surface of the oil drum, it is difficult to use a crane to assist in the movement, which affects the work efficiency.

[0004] In the process of lifting oil drums using oil drum grabbers, there is a problem with existing hook structures, such as those described above. When the hook body below the hook contacts the oil drum, the oil drum's outer shape causes the contact area to be affected by the drum's shape, resulting in a small contact area. This leads to slippage of the hook when gripping the oil drum, resulting in poor stability of the hook during oil drum transportation. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art where, when the hook and the oil drum come into contact with each other through the structure of the hook itself, the contact area is affected by the shape of the oil drum, resulting in a small contact area. This causes the hook and the oil drum to slip when gripping the oil drum, resulting in poor stability of the hook and the oil drum during transportation. Therefore, a small oil drum gripping hook anti-slip structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a small oil drum gripping hook anti-slip structure, comprising a body and a rotating shaft, wherein the rotating shaft is fixedly connected to the inner wall of the hook body, and a gripper is rotatably connected to the surface of the rotating shaft, the gripper being located inside the hook body, a locking pin is installed on the inner wall of the hook body, a chain is installed on the surface of the locking pin, and auxiliary components are provided on both sides of the hook body, the auxiliary components comprising a mounting frame, the mounting frame being rotatably connected to the outer circumference of the rotating shaft, a connecting plate being fixedly connected to the side surface of the mounting frame, a baffle being fixedly connected to the side of the connecting plate away from the mounting frame, and a damping pad being fixedly connected to the side of the baffle away from the connecting plate;

[0007] The auxiliary component also includes a lifting protrusion, which is fixedly connected to the side surface of the rotating shaft. A fixed gear is fixedly connected to the side of the lifting protrusion away from the rotating shaft. A mounting cavity is formed on the side surface of the mounting bracket. A T-shaped bracket is slidably connected to the inner wall of the mounting cavity. A limit spring is fixedly connected to the side surface of the protrusion of the T-shaped bracket. The end of the limit spring away from the protrusion of the T-shaped bracket is fixedly connected to the inner wall of the mounting cavity. A connecting plate is fixedly connected to the side surface of the T-shaped bracket. A fixing pin is fixedly connected to the side surface of the connecting plate. The fixing pin is inserted into the tooth groove of the fixed gear.

[0008] Preferably, a handle is fixedly connected to the side of the connecting plate away from the fixing pin, which allows the user to hold the plate and pull it, thereby making it easier for the staff to pull the connecting plate and the fixing pin to lose its locking effect.

[0009] Preferably, a reinforcing rib is fixedly connected to the side surface of the fixing pin, and the reinforcing rib is fixedly connected to the side surface of the connecting plate. The reinforcing rib can increase the structural strength of the connection between the fixing pin and the connecting plate, thereby improving the stability of the fixing pin when locked.

[0010] Preferably, the inner wall of the mounting frame is fixedly connected with a second reinforcing rib. The second reinforcing rib can increase the structural strength of the bending part of the mounting frame, thereby improving the stability of the mounting frame structure and increasing the load capacity of the mounting frame.

[0011] Preferably, the baffle is arc-shaped, and there are two baffles. The two baffles are symmetrically arranged about the vertical center line of the hook body. The baffles can increase the contact area between the hook and the oil drum when the hook grabs the oil drum, thereby increasing the stability of the hook when grabbing the oil drum.

[0012] Preferably, the lifting protrusion is located inside the mounting bracket, and the fixing pin is slidably connected to the inner wall of the mounting bracket. The lifting protrusion can fix the position of the fixing gear and increase the height of the fixing gear to ensure that the fixing gear and the fixing pin are on the same plane.

[0013] Preferably, there are two T-shaped brackets, which are arranged symmetrically about the horizontal center line of the connecting plate. The T-shaped brackets and the limiting spring can constrain the position of the connecting plate to ensure the stability of the connecting plate in the locked state, and can also lock the position of the fixing pin installed on the connecting plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting auxiliary components, the contact area between the hook and the oil drum is increased when the hook picks up the oil drum, thereby improving the anti-slip effect of the hook, reducing the problem of the hook slipping easily when picking up the oil drum due to the small contact area between the hook and the oil drum, and further improving the stability of the hook during use.

[0023] Please see Figures 1-6This utility model provides a technical solution: a small oil drum gripping hook anti-slip structure, including a body and a rotating shaft 2. The rotating shaft 2 is fixedly connected to the inner wall of the hook body 1. A gripper 3 is rotatably connected to the surface of the rotating shaft 2. The gripper 3 is located inside the hook body 1. A locking pin 4 is installed on the inner wall of the hook body 1. A chain 5 is installed on the surface of the locking pin 4. Auxiliary components 6 are provided on both sides of the hook body 1.

[0024] In this embodiment: the auxiliary component 6 includes a mounting frame 61, which is rotatably connected to the outer circumference of the rotating shaft 2. A connecting plate 62 is fixedly connected to the side surface of the mounting frame 61. A baffle 63 is fixedly connected to the side of the connecting plate 62 away from the mounting frame 61. A damping pad 64 is fixedly connected to the side of the baffle 63 away from the connecting plate 62.

[0025] The auxiliary component 6 also includes a lifting protrusion 65, which is fixedly connected to the side surface of the rotating shaft 2. A fixed gear 66 is fixedly connected to the side of the lifting protrusion 65 away from the rotating shaft 2. A mounting cavity 67 is opened on the side surface of the mounting bracket 61. A T-shaped bracket 68 is slidably connected to the inner wall of the mounting cavity 67. A limit spring 69 is fixedly connected to the side surface of the protrusion of the T-shaped bracket 68. One end of the limit spring 69 away from the protrusion of the T-shaped bracket 68 is fixedly connected to the inner wall of the mounting cavity 67. A connecting plate 610 is fixedly connected to the side surface of the T-shaped bracket 68. A fixing pin 611 is fixedly connected to the side surface of the connecting plate 610. The fixing pin 611 is inserted into the tooth groove of the fixed gear 66.

[0026] Specifically, a handle 612 is fixedly connected to the side of the connecting plate 610 away from the fixing pin 611. The handle 612 allows the user to hold the plate, making it convenient for the staff to pull the connecting plate 610 and pull the fixing pin 611, thereby causing the fixing pin 611 to lose its locking effect.

[0027] Specifically, the side surface of the fixing pin 611 is fixedly connected with a reinforcing rib 613, and the reinforcing rib 613 is fixedly connected to the side surface of the connecting plate 610.

[0028] In this embodiment, the structural strength of the connection between the fixing pin 611 and the connecting plate 610 can be increased by the reinforcing rib 613, thereby improving the stability of the fixing pin 611 when locked.

[0029] Specifically, the inner wall of the mounting bracket 61 is fixedly connected with a reinforcing rib 614. The reinforcing rib 614 can increase the structural strength of the bending part of the mounting bracket 61, thereby improving the stability of the mounting bracket 61 structure and increasing the load capacity of the mounting bracket 61.

[0030] In this embodiment: the baffle 63 is arranged in an arc shape, and there are two baffles 63. The two baffles 63 are arranged symmetrically about the vertical center line of the hook body 1.

[0031] In this embodiment, the baffle 63 can increase the contact area between the grab hook and the oil drum when the grab hook grabs the oil drum, thereby increasing the stability of the grab hook when grabbing the oil drum.

[0032] Specifically, the lifting protrusion 65 is located inside the mounting bracket 61, and the fixing pin 611 is slidably connected to the inner wall of the mounting bracket 61. The position of the fixing gear 66 can be fixed by the lifting protrusion 65, and the height of the fixing gear 66 can be increased to ensure that the positions of the fixing gear 66 and the fixing pin 611 are on the same plane.

[0033] Specifically, there are two T-shaped frames 68, which are arranged symmetrically about the horizontal center line of the connecting plate 610.

[0034] In this embodiment: the position of the connecting plate 610 can be constrained by the cooperation of the T-shaped bracket 68 and the limiting spring 69 to ensure the stability of the connecting plate 610 in the locked state, and at the same time, the position of the fixing pin 611 installed on the connecting plate 610 can be locked.

[0035] Working principle: When using the hook to pick up the oil drum, push the upper end of the gripper 3 towards the chain 5. Under the constraint of the rotating shaft 2, the gripper 3 rotates in the specified direction and gradually unfolds. After the gripper 3 unfolds, place the clamping area formed by the gripper 3 and the hook body 1 on the protruding part of the upper edge of the oil drum. After the placement is completed, pull the gripper 3 backward. The gripper 3 is reset by force and works with the hook body 1 to clamp the oil drum. After the clamping is completed, the oil drum can be transferred.

[0036] Before using the grab hook, adjust the position of the baffle 63 according to the angle of the grab hook in its placement state. When adjusting the baffle 63, pull the handle 612. The handle 612 pulls the connecting plate 610. The connecting plate 610 is forced to pull the T-shaped frame 68 and the fixing pin 611. The T-shaped frame 68 is forced to compress the limiting spring 69. The limiting spring 69 is compressed and deformed. The fixing pin 611 is pulled by the connecting plate 610 to disengage from the tooth groove of the fixing gear 66 and loses its lock on the connecting plate 610. When the connecting plate 610 loses its lock, push the handle 612 along the axis of the rotating shaft 2. The handle 612, together with the connecting plate 610 and the T-shaped frame 68, pushes the mounting frame 61. The mounting frame 61, together with the connecting plate 62, moves the baffle 63 and the damping pad 64. The baffle 63 changes its own angle during the movement.

[0037] When the angle of the baffle 63 changes to be parallel to the surface of the oil drum, release the handle 612. The handle 612 loses the force applied to the connecting plate 610, the connecting plate 610 loses the tension on the T-shaped bracket 68, the T-shaped bracket 68 loses the pressure applied to the limit spring 69, and the limit spring 69 rebounds without pressure, pulling the connecting plate 610 back to its original position in conjunction with the connecting bracket. During the resetting process, the connecting plate 610 pulls the fixing pin 611. After the fixing pin 611 is reset, fine-tune the mounting bracket 61 according to the position of the reset pin so that the fixing pin 611 is re-inserted into the tooth groove of the fixing gear 66. 611 is reinserted into the tooth groove, which, together with the fixed gear 66, connecting plate 610, and T-shaped frame 68, locks the positions of the mounting frame 61, connecting plate 62, and baffle 63. Then, when the hook picks up the oil drum, the baffle 63 and damping pad 64 increase the contact area between the hook and the oil drum. By setting the auxiliary component 6, the contact area between the hook and the oil drum is increased when the hook picks up the oil drum, which improves the anti-slip effect of the hook and reduces the problem of the hook slipping easily when picking up the oil drum due to the small contact area between the hook and the oil drum. It also further improves the stability of the hook during use.
